To a 20 mL vial was added a solution of 4-{4-(4-chlorobenzyl)-5-[1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl]-1,3-thiazol-2-yl}pyridine (0.2245 g, 0.635 mmol) in anhydrous tetrahydrofuran (2.000 mL) and methanol (2.000 mL). 4.0 M Hydrochloric acid in 1,4-dioxane (1.0 mL, 4.0 mmol) was added and the reaction mixture was allowed to stir at 50° C. for 18 hours. The reaction was cooled to ambient temperature and quenched by the addition of a saturated aqueous solution of sodium bicarbonate (10 mL) and extracted with EtOAc (10 mL×3). The combined organic phases were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The crude material was purified by HPLC to afford the product (0.0423 g, 45%) as an off white solid. LC/MS (AA) ES+ 354. 1H NMR (400 MHz, d6-DMSO) δ: 14.48 (s, 1H), 8.71 (dd, J=4.4, 1.2 Hz, 2H), 7.89-7.87 (m, 2H), 7.38-7.32 (m, 4H), 4.67 (s, 2H).
